Narrated Ibn `Umar:
The Prophet (ﷺ) said, "Whoever manumits his share o a jointly possessed slave, it is imperative on him to manumit the slave completely if he has sufficient money to pay the rest of its price which is to be estimated justly. He should pay his partners their shares and release him (the freed one).
Narrated `Abdullah bin `Umar:
Allah's Messenger (ﷺ) said, "Whoever frees his share of a common slave and he has sufficient money to free him completely, should let its price be estimated by a just man and give his partners the price of their shares and manumit the slave; otherwise (i.e. if he has not sufficient money) he manumits the slave partially."
Narrated Qais:
Bilal said to Abu Bakr, "If you have bought me for yourself then keep me (for yourself), but if you have bought me for Allah's Sake, then leave me for Allah's Work."
Narrated Qais:
When Abu Huraira accompanied by his slave set out intending to embrace Islam they lost each other on the way. The slave then came while Abu Huraira was sitting with the Prophet. The Prophet (ﷺ) said, "O Abu Huraira! Your slave has come back." Abu Huraira said, "Indeed, I would like you to witness that I have manumitted him." That happened at the time when Abu Huraira recited (the following poetic verse):-- 'What a long tedious tiresome night! Nevertheless, it has delivered us From the land of Kufr (disbelief).
